Gilmour Circular Sprinkler with Base

Gilmour Circular Sprinkler with Base – Model #4200 Specifications

How large of a lawn can this sprinkler cover?
In full-circle mode, the Gilmour Model #4200 delivers a 42.5-foot spray distance and can cover up to 5,670 square feet from a single placement. For lawns larger than this, simply reposition the sprinkler or chain multiple units together using the built-in multi-connection outlets on the base.

Can I water just part of my yard — like a corner or a half-circle?
Yes. The adjustable collar lets you configure the spray from a narrow partial arc up to a full 360° circle. This is particularly useful for corners, edges, or any lawn shape that isn't a perfect open circle — you get targeted coverage without spraying water onto driveways, sidewalks, or garden beds.

What does the diffuser pin do?
The diffuser pin controls spray force. Adjusting it shifts the output from a powerful, far-throwing jet to a soft, gentle mist. The gentle mist setting is useful when watering delicate plants near the perimeter of the lawn or for reducing drift on windy days. For maximum coverage distance, use the jet setting.

Is this sprinkler appropriate for newly seeded or freshly sodded lawns?
Gilmour recommends this sprinkler for large, mature lawns. If you have newly seeded areas, the diffuser pin can soften the spray to a mist, but for very delicate new growth you may want to consider an oscillating sprinkler like the Gilmour Oscillating Sprinkler for a gentler, rain-like application while turf gets established.

Can I automate this sprinkler so it runs on a schedule?
Absolutely. This is a standard hose-end sprinkler with a garden hose thread connection. Simply add a battery-operated hose-end irrigation timer between your faucet and the hose, and you can program it to water at specific times and durations without having to be home.

How do I connect multiple sprinklers or hoses?
The base includes multiple connection outlets, so you can attach additional hoses or sprinklers inline to extend coverage to multiple areas of the yard in a single watering session. This is especially practical for large properties where one sprinkler placement won't cover the entire area.

What is the difference between this sprinkler and the Gilmour Tripod Sprinkler?
The Model #4200 sits directly on the ground on its weighted base — ideal for flat, open lawns with no obstructions. The Gilmour Adjustable Circular Tripod Sprinkler elevates the sprinkler head up to 58 inches on a telescoping tripod, making it a better choice when mature shrubs, ornamental grasses, or other plantings would block a ground-level spray pattern.

What if I need to water an irregularly shaped lawn?
For truly custom spray patterns that match non-circular or unusual yard shapes, consider the Gilmour 196SPB Pattern Master Sprinkler, which uses a flexible ring with 12 individually adjustable pegs to sculpt the spray pattern to match virtually any lawn shape.

Does this work with my existing garden hose?
Yes. The Gilmour Model #4200 connects to any standard garden hose with a standard threaded fitting — the same connection used on nearly every outdoor spigot. No special adapters are needed.
